Dropbox works well for certain documents that you want access to, the only problem being that the document must be in your Dropbox folder.

You can symlink and folder to Dropbox and that will sync it with the original folder in place. For example, the Terminal command below will symlink the ~/Documents folder to Dropbox. Anything placed in the ~/Documents folder will be synced to Dropbox.

Not sure exactly what folders or tasks OP is trying to accomplish here, but this might do the trick.

It might sound obvious (that's strike two for me tonight) but why not using the already available rsync command and the "remote login" functionality? (Settings => Sharing Panel).
Unless of course you're not comfortable with command line (I'm sure there are rsync GUIs out there though).
You use that in conjunction with a daemon or a script in any language and you got yourself a free and "built in" way to sync between macs.
